Where to Put a 3D Printer: Desk, Cabinet, Noise and Living Space
are explained briefly when you hover over or tap them.
A 3D printer often runs for hours, makes noise, gets hot and gives off particles and gases. Where it stands therefore decides print quality, safety and whether it gets in the way in everyday life. This article is the counterpart to Laser in the home: what you should sort out before the printer gets its permanent spot.
The spot at a glance
| Point | What to look for |
|---|---|
| Surface | stable, level, non-flammable, no papers or curtains nearby |
| Room | can be ventilated, no draught directly on the printer, not damp |
| Distance | not right next to where you sit, not in the bedroom |
| Cabinet | only with heat dissipation and nothing flammable inside |
| Safety | smoke alarm in the room, socket without an overloaded power strip |
Surface and desk
The printer needs a stable, level surface. Creality states in its manuals that strong vibrations and an unstable stand reduce print quality. A wobbly table transfers the vibrations of fast movements into the print, see also Your first 3D print.
- Plan for the weight: According to the manufacturer, a Bambu Lab A1 weighs 8.3 kg, an enclosed Anycubic Kobra S1 18 kg and a Prusa CORE One+ 22.5 kg. Large machines with a heated chamber weigh over 30 kg. A light shelf board is not made for that.
- Bed slingers need room to move: On open printers such as the A1, the bed moves out to the front and back. Space must be left free in front of and behind the machine.
- Non-flammable base: For schools, the DGUV (the German statutory accident insurance) recommends a fireproof base and no flammable objects such as notepaper or curtains close by, especially when the printer runs unattended. The same applies at home. A stone slab or tile under the machine is a simple solution.
- Distance from the wall: Fans and exhaust openings must not be blocked. How much clearance is needed is stated in your machine’s manual.
Room climate
In its manuals, Creality recommends a well-ventilated, cool and low-dust place, away from heat sources and from flammable or explosive substances. A few practical points:
- No draughts: An open window or an air conditioner directly at the printer makes parts cool unevenly. Corners lift, see Warping.
- No heat sources: Creality explicitly mentions keeping away from heat sources. These include radiators and a spot in full sun.
- Humidity: Many filaments absorb water from the air. In damp cellars a dry box is worthwhile, see Drying filament.
Cabinet and enclosure
A cabinet or an enclosure dampens noise, keeps dust away and protects against curious hands. Prusa gives exactly these reasons, plus protecting children and pets from hot parts. There are, however, three points you must keep in mind.
1. Heat. In a closed space, the heat of the print bed builds up. For ABS, ASA and nylon this is intended. PLA and PETG, on the other hand, tolerate raised temperatures badly. Prusa writes that manufacturers therefore often recommend removing the top cover or leaving the door open for PLA, Prusa itself included for the MK4S enclosure. According to the manufacturer, the Prusa CORE One is built so that PLA works with the door closed, but a small ventilation opening at the top has to be left open. If you put an open printer in a cabinet, the rule for PLA is therefore: the heat must be able to escape.
2. Power supply and electronics. For its enclosure made from IKEA Lack tables, Prusa points out that the power supply has to sit outside, because the temperature behind acrylic glass walls would otherwise be above the power supply’s recommended operating temperature. According to Prusa, this is not necessary with a tent made of porous fabric, because it does not get as warm.
3. Fire safety. A wooden cabinet is itself flammable. The DGUV names overheating of the machine and flammable objects nearby as fire hazards. For the cabinet this means:
- no filament stock, boxes, papers or cleaning agents on the same shelf
- a non-flammable base inside the cabinet
- a smoke alarm in the room, ideally positioned so that it also notices smoke coming from the cabinet
- do not crush cables, keep the socket accessible
Ventilation. A closed cabinet does keep emissions inside, but they come out when you open it. Without a filter or extraction they otherwise build up. Which filters do what is covered under Enclosures and air filters.
Noise
According to Prusa, noise comes mainly from the movement of the axes and from vibrations. Some manufacturers state values in decibels:
| Machine | Manufacturer’s figure |
|---|---|
| Anycubic Kobra S1 | at most 46 dB in standard mode, at most 44 dB in quiet mode |
| Flashforge Adventurer 5M Pro | 55 dB in standard mode, 50 dB in quiet mode |
| Bambu Lab A1 | below 48 dB in quiet mode (manufacturer’s page) |
| Bambu Lab A1 mini | below 48 dB in quiet mode (manufacturer’s page) |
None of the manufacturers states a measuring distance or measuring conditions. The values are therefore only roughly comparable.
What also helps:
- Enclosure: Prusa writes that an enclosure can reduce the noise enough that you can sit next to it without hearing the printer.
- Quiet hours: In Germany, night-time quiet generally applies from 10 pm to 6 am. Read your house rules if the printer is to run at night in a flat with thin walls.
For schools, the DGUV also names reduced ability to concentrate because of the noise level as a hazard. If you work at the same desk, you will notice this quickly.
Emissions: what the research says
When filament is melted, ultrafine particles and volatile organic compounds are produced. The most important findings from German authorities:
- BfR: The Federal Institute for Risk Assessment detected particles from PLA with a size of around 50 nanometres. They are so small that they reach the alveoli in the lungs. The higher the printing temperature, the more particles were produced. The BfR is still investigating whether they pose a health risk.
- UBA and BAM: In a study commissioned by the Federal Environment Agency, particles occurred practically only during the heating phase. Once printing began, the rates dropped quickly. Filaments of the same base material from different manufacturers can differ significantly.
- IFA (DGUV): According to current knowledge, the guide values for indoor spaces are met if the room is ventilated regularly and sufficiently and the material is not heated above its decomposition temperature.
What this means in everyday use is covered in detail under Safety in 3D printing. The short version: air the room thoroughly after every print, as the DGUV also recommends, do not sit directly next to a running printer and do not print hotter than necessary.
Bedroom and living room
For schools, the DGUV recommends setting the printer up in a room of its own that is not permanently used as a classroom. Applied to the home, that means: not where you spend many hours at a stretch.
Our recommendation, not a rule: no printer in the bedroom. You spend many hours there with the window closed, ventilating during a print disturbs print quality, and night prints mean noise and a source of fire next to your bed. This applies even more to a child’s room.
| Room | Advantages | What to watch out for |
|---|---|---|
| Home office | heated, dry, usually has a window | distance from the desk, ventilate regularly |
| Hobby room, workshop | a room of its own, noise bothers nobody | check temperature and humidity, smoke alarm |
| Cellar | far from the living area | often cold and damp, window needed for ventilation |
| Living room | space, often easy to ventilate | noise, emissions where you spend a long time |
| Bedroom, child’s room | none | not suitable |
Open or enclosed
| open printer | enclosed printer | |
|---|---|---|
| Materials | PLA, PETG, TPU | additionally ABS, ASA and nylon, depending on the machine |
| Noise | sound undamped | somewhat quieter thanks to the enclosure |
| Emissions | spread directly into the room | stay in the enclosure, come out when you open it; some machines have filters, for example the Adventurer 5M Pro with a HEPA and activated carbon filter according to the manufacturer |
| Children and pets | hot and moving parts freely accessible | build volume protected |
| PLA in summer | unproblematic | heat build-up possible, follow the manufacturer’s notes on opening |
For schools, the DGUV recommends machines whose build volume is protected against accidental reaching in. If you have children or pets in the household, you benefit from this at home too.
Resin printers in the home
A resin printer makes different demands from a filament printer:
- Gases instead of particles: In the UBA study, no particle emissions could be detected from the resin printer and the post-curing unit. An investigation by UL Chemical Insights, on the other hand, found 3 to 6 times higher emissions of volatile organic compounds than the average for filament printing. During washing, most of it came from the isopropanol.
- Warmth: Cold resin prints badly. Manufacturers mostly recommend at least 20 °C, the values are listed under Resin types. A cold cellar is therefore a poor place.
- Isopropanol is highly flammable: no fan heaters or open flames nearby, keep containers closed.
- Light: Resin cures under sunlight, which is why manufacturers store it protected from light. Do not put the printer in the sun by the window.
- A room of its own: For workplaces, the BG ETEM recommends a separate room and regular ventilation.
Details on gloves, ventilation and disposal are under Safety with resin printing.
In short
- A stable, level, non-flammable surface, nothing flammable beside it.
- In a cabinet: let heat escape, especially with PLA, keep the power supply out of the heat build-up, no filament store on the same shelf.
- Manufacturers’ dB figures without a measuring distance are only roughly comparable.
- Air the room thoroughly after every print, do not sit next to the running printer.
- Not in a bedroom or child’s room.
- Resin printer: warm, ventilated, dark, no ignition sources.
